HAIRPIN.

Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed. November 5, 1920. Serial No. 421,982.

To all whom it may concern Be it known that I, EDWARD B. DEWEY, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain'new and useful Improvements in Hairpins; and I hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which form part of this specification.

This invention is a novel hairpin which can be readily inserted in and removed from the hair; and which when inserted in the hair will not catch the hair or hair net or break or tear the hair or hair net; which will effectively retain its position and support and retain the hair; and which is also admirably adapted for use as an invisible p The present invention provides a hairpin of such form that as it is inserted into the hair it tends to alternately open and close, or expand and contract, thus insuring its properly grasping the hair, and when it is inserted in place it will practically remain in position, neither unduly expanded nor unduly contracted, and by reason of its peculiar form will be effectively retained in the hair in the most advantageous manner.

I will explain the invention with reference to the accompanying drawings, illustrating such pin, and summarize in the claims the invention for which protection is desired.

In said drawings;

Figure 1 is a front View of the preferred form of hair pin.

Fig. 2 is an edge view of one side of the in. p Fig. 3 is an edge View of the other side of the pin. 1

The hairpin is preferably made of tempered wire and has opposite substantially parallel side members 1 and 2, connected at the top by a bend 3. As shown the side member 1 has two inwardly projecting bends 1 and 1, which are arranged approximately equidistant between the bend 3 and lower extremity of the member; and the member 2 has an inwardly projecting bend 2", which is preferably arranged at a point intermediate and equidistant from the bends 1, 1 All of these bends preferably lie in the same horizontal plane so that the pin is fiat when viewed from the side (see Figs. 2 and 3).

Preferably the bends 1, 1 2 are of such depth that they will project slightly more than one-half way across the normal width of the pin, so that in normal position the inner parts of the bends will naturally tend to retain the hair which lies between the side members of the pin.

The side members are straight above, between and below the bends, and the extremities of the members 1 and 2 at the mouth of the pin are slightly flared or bent inwardly as shown at 1 2 respectively. These inwardly curved ends of the pin have a tendency to cause the mouth of the pin to contract or partly close as it is inserted in the hair. The closing tendency of the pin caused by the ends 1 and 2 is intermittently counteracted as the pin is inserted in the hair by the bends in the side members of the The particular number of the bends and the particular form of such bends in the sides of the pin might be varied, provided the essential operative features of the invention are retained.

' Hairpins made according to this invention have no part which will catch the hair or hair nets, or break or tear the hair or nets; as the bends are not abrupt and are smoothly finished.

When such a hairpin is inserted into the hair the short ends 1 and 2 tend to cause the mouth of the pin to close on the hair passing between the side members, but each alternate bend tends to cause the mouth of the pin to open slightly, but as soon as the hair passes a bend the inturned ends 1, 2 tend to cause the mouth to again contract; thus when the pin is fully inserted the side members of the pin assume their normal position, and the inwardly curved ends and bends effectively retain the pin in position in the hair.

The hairpins are preferably made of wire but could be formed of any other suitable material, such as is commonly used in the manufacture of hairpins.

I claim:

1. A hairpin having oppositely disposed side members formed with inwardly projects ing bends which alternate in position and extend approximately half the normal width of the pin, said side members being straight above and between the bends, and the lower portion of each side member extending straight below the bend and having its extremitycurved inwardly, the inwardly curved extremities tending to cause the mouth of the pin to close as it enters the hair and counteracting the tendency of the bends to spread the members apart, substantially as described. v

2. A hairpin having oppositely disposed side members, one of said members having two inwardly projecting bends and the other member having one inwardly projecting bend midway between the bends in the opposite side member, the members being straight above between and below the bends, the extremities of the members being inwardly curved and tending to cause the hair pin to close when the pin is inserted in the hair and cause the inwardly projecting bends to retain the pin in the hair.

3. A'hairpin having oppositely disposed side members, one of said members having two inwardly projecting bends and the other member having one inwardly projecting bend intermediate the bends in the opposite member, the lower portions of the side members extending straight below the bend and each having its extremity curved inwardly, the inwardly curved extremities tending to cause the mouth of the pin to close as it enters the hair and counteracting the tendency of the bends to spread the members apart, substantially as described.

In testimony that I claim the foregoing as my own I aifix my signature.
